Interesting - looks like this converts USB to SPDIF coax

Not sure if there is a need for this - but I stumbled on to it...passing it on...

Wonder what this would do on a unmodded UA-5 USB port...?

Reading some of the associated links - one gets the idea that this device was created so you can get an SPDIF signal from a USB port on a computer  - so you can drive whatever existing DAC you might have (most of which would have coax-in)
